LUMINOUS REFLECTION SIGN.

Application filed October 30, 1923. Serial No. 671,703.

T 0 all whom it may concern:

Be it known that we, GUILLERMO DOUGLAS PALMER, a citizen of Argentina,and Josr': FERNANDEZ CASTILLO, a subject of the King of Spain, both.residing at Buenos Aires, Argentina, have invented a LuminousReflection Sign, of which the following is a specification.

' The present invention refers to a new luminous apparatus, particularlysuitable for use with radiator caps on motor cars.

It may be used advantageously, not only as an adornment of the vehicleswhich will carry it, but also as a means of identification or foradvertising purposes, as will be seen from the following description.

In the accompanying drawings Figure l is a front view of the apparatus,and Figure 2 a longitudinal section of the same, on the line AB ofFigure 1.

vlVithin a metal frame 1 which may be octagonal or of any otherconvenient shape, a thick glass plate 2 is fixed, into which are carvedthe letters or signs 3 which are to be illuminated; another mode ofconstruction being to raise said letters or signs,

The frame holding the glass plate comprises a flanged base member 4which has a tubular, exteriorly threaded part 5 upon which the nut 6 isscrewed.

By means of this screw 5 the whole construction can be firmly secured bypassing the threaded part through a perforation in the radiator cap 7.The radiator cap can also be substituted by a staple which, by means ofan arm and screws, the device can be attached to any other part of themotor car.

The member 4 is hollow. To the interior of the part 5 is screwed a plug8, so as to be opened easily, and this plug retains in the interior ofthe member an electric lamp 9 of convenient power, the wires 10 of.which are connected with the socket 11 for thereception of a contactplug 12.

Between the frame and the member, a slot 13 has been left which fpermitsthe insertion of a colored glass or lm so as to give to the letters orsigns the color illumination especially desired. The same effect can beobtained by the use ofcolored lamps or by coloring directly the lettersand signs.

The glass plate into which the letters or signs are carved, can becolored or colorless.

At all events, the illumination of the signs or letters by means of thereflection of the beams issuing from the luminous centre which isinvisible, being contained in the interior of the member 4, is highlyattractive and, up to now, it has not been used at all with motor cars.

It is self-evident that the dimensions of the apparatus and the placewhereit will be located, can vary in accordance withthe.

taste of its owner, but the most convenient seem to be the radiator cap,the wind shield and similar places; as to the radiator cap it will besuflicient to perforate it and secure the apparatus by means of themember and the nut 6.

We claim- 1. A luminous reflectionsign comprising a glass, a framesupporting the latter at its edges, a base for the frame having a li htpassage extending therethrough to the e ge of the glass, a tubularextension below the base forming a pocket for an electric lamp, andmeans on the extension co-operating with the base for clamping thelatter to a support. 2; A luminous reflection sign comprising a hollowbase member, having a slide receiving slot therein, a frame mounted onthe base member, a transparent sign panel mounted in the frame, anexteriorly threaded tubular member extending below the base member, andcommunicating with the frame through the base-member, an electric lampmounted in the tubular extension, a nut on the latter cooperating withthe base member to constitute a clamping means, a lamp support inthreaded connection withthe bottom of the tubular extension, and meansfor connecting the lamp with an electric current supply.
